Sinking/Sourcing Mode Selection for Safe Disable Inputs

Note: Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to EN61800-5-1, ISO13849
Cat. 3, IEC/EN61508 SIL2, Insulation coordination: class 1.
Use jumper S3 on the terminal board to select between Sink mode, Source mode or external power supply for the Safe Disable
inputs H1 and H2 as shown in

Using the Pulse Train Output

The pulse train output terminal MP can supply power or be used with an external power supply.
NOTICE: Connect peripheral devices in accordance with the specifications. Failure to comply may cause unexpected drive operation, and
can damage the drive or connected circuits.
n Using Power from the Pulse Output Terminal (Source Mode)
The high voltage level of the pulse output terminal depends on the load impedance.
Load Impedance R
Note: The load resistance needed in order to get a certain high level voltage V
